I was unable to find any explanation of this function in the usual places. Does anyone know what this option does?

Thanks!

This option provides a way for HAT’s (that support it) to disable output when there is not audio signal.

Thanks Harry!

@spockfish if there is no HAT, and I just have a DAC connected by USB, what does this option do?

What scenarios is it a bad idea to have it on?

Thanks!

DAPM is a ‘HAT only’ thingie: it makes it possible (if the chipset used on the HAT supports it/is supported) to power down the output (and the chipset) if there’s no signal.

Many thanks!

Now i have to figure out if my Pi2AES supports it!
